QUALITY ASSURANCE
1. No Leakage!
Client: “Oil leaks are considered critical failures in a hydraulic system.
Leaks can be a safety issue on equipment because the system does
not hold pressures at designed levels.”
What’s JB doing:
(1) Casting Simulation applied prior to designing
to minimize the possibility of porosity and shrinkage.
(2) 100% Ultra-Sonic Test or Radiographic Test on castings.
(3) 100% Liquid Pressure Test after machined.
2. No burrs!
Client: “Contamination has become a major focus for
(1)Un-fixed bur-removing tool installed on machines.
3. No tolerance beyond!
What’s JB doing:
ULTRASONIC DETECTOR
SPECTROMETER
METALLURGICAL INSTRUMENT
ROUGHNESS TESTER
TENSILE TESTING MACHINE
CMM MACHINE
OEM equipment manufacturers in the past 5 years.
This requirement exists throughout the fluid power
industry. ”
(2)Detailed de-bur work instruction is applied for every process.
(3)Special manual de-bur tool is available for un-reachable corners.
Client: “ Material specification and dimensional compliance to engineering drawings is expected to be 100%. This is not a negotiable point for any application in our industry.”
(1)Meterial Tracibility No. is cast or engraved on each part, to track all the chemical & mechanical properties, metallic phase data, which are kept for 3 years.
(2)PPAP (Production Part Approval Process)Products in the first delivery or design changes or any process, material change or variation of the manufacturing process shall, in accordance with the procedural requirements to inspect the sample
(3)SPC(Statistical Process Control)SPC is a class of feedback systems, use of data statistics, trends, to better understand the process changes in order to find out any instant non-conforming and react by a reasonably way to reduce quality problems
